A seat back 10 for a vehicle includes a frame 14 and an electronic display 16. A pyrotechnic fastener 18 supports the electronic display on the frame. The pyrotechnic fastener includes a first portion (20, figure 5) fixed to the frame, a second portion (22) fixed to the electronic display, and a pyrotechnic element (24). During a frontal impact of the vehicle, the pyrotechnic element may be activated to lower the electronic display (figure 6) resulting in increased travel space for the occupant. The display may be lowered under the force of gravity and/or from impact with an occupants head. The seat back may be provided with a guide 44 which receives the second portion of the fastener, where the second portion moves along a slot 46 in the guide when dropping to the second position. A controller may be provided to activate the pyrotechnic element in response to a sensed vehicle crash.
